CASEIVIENUVTINDOW ADJUSTER.

application nled. January 9, 1923.

'l`his invention relates lo Casement window adj usters and more particularly to a device olf this character wherein a swingingl rod is attached to either the window frame or the window and is lirictionally connected to the other of these two members, so that the wimlow may be held in any desired adjusted open position.

1t is, o1. course, desirable to provide a device oit this (':haracter such that when the window has been opened or closed to any desired extent it will be lirmly held in this position without the necessity ot any screw or clamp by which the parts may be tight cned; that is to say, while the window `will i auton'latic:.lly held in any adj usted posiH tion against movement by any ordinary iiorce which might be applied thereto by' the wind, its movement may, however', be readily ellected when the window is grasped and moved, positively to another' position.

@ne object ot my invention is to provide an improved window adjuster oit this type.

Another object oi my invention is to providea window adjuster ot this description, which shall be simple in construction and economical to manutactu re, while at the same time possessing` the required elliciency o if operation.

Another object olf my invention to pr'ovide a window adjuster of this ijlescription such that there will be very little, :it any, tendency for the partsI to wear, and when once installed will give etlicient service over a long` period oit time.

Another object of this invention is to provide a window adjuster of this character so arranged that any slight wear which may occur in the trictional element will be automatically taken up and the required amount oil.1 friction will always he maintained between the parts.

'llo these and other ends the invention consists in the novel features and combinations el parts hereinafter described and claimed.

liig. 1 is a fragmentary, front elevational view of a easement window provided with an adjuster embodying my invention.

131g. 2 :is a top plan view of the parts shown in Fig. 1.

l? 3 is an enlarged top plan view oit my improved easement window adjuster.

Serial N'o. 611,657'.

Fig. 4l is a sectional Vview on line -1-L1 o1 Fie' 3 vcntion which, l have chosen to illustrate in the drawings, a easement window is shown at 10, hinged to the :trame 11 in the usual way. Upon the window trame 11 is pivoted at 12 one of the members oit my improved adjuster, consisting of' the swinging; rod 1&5. 'lhis rod may bc pivoted in any preferred manner to a plate or other support 141-. se cured `to the window frame.

lUpon the window itself is secured a bracket 1G, which is provided with a horizontally disposed plate 17, upon which is pivoted an upstandingyoke 18 by means olf the rivet or pin 19.

blurroundine` the rod 13 and `within the two upstamling legs 2() and 21 oit the yoke .is asplit libre collar or washer 22, which closely embracesI the rod 13. ldifirrounding.;- the libre washer Q2 is a collar 23, which may he and usually is formed oit metal. and is open or split at 24 so that it may be tempered to clamp upon the libre washer and cause :it to `tigjhtly embrace the rod. lt will be apparent that the collar 23 acts as a spring to always maintain the washer clamped tightly upon the rod 13 so as to ii'ictionally hold this rod against movement through the yoke.

If a washer becomes sli glitly worn by lon and continued use, the spring action oil' the collar Vwill take u1 such wear and always keep the washer clamped frictionally against the rod, whereby the adjuster will always operate elliciently and with certainty. The. upstanding legs and 21 of the yoke prevent any longitudinal movement oit' the libre washer relative to the window, and the pivotal connection of the yoke with the plate 17 permits any slight turning movement of this yoke which is necessary to compensate for the sli ght angular change which may take place betweeifi the window and the rod 13. l

lNhile my window adjuster is very simple in construction and economical to manufaeture, it is, of course, at the same time very etlicient in operation and very durable, and

tl O

the Window to which it is applied may be opened to any desired extent and it will be firmly and securely held in this position until the Window is positively moved to another position.

Vhile I have shown and described a preferred embodiment of my invention, it will be obvious that it is not limited to the exact details shown but is capable of modification and Variation Within the spirit of the invention and the scope of the appended claims.

Vhat I claim is:

1. A easement Window adjuster comprising a rod adapted to be pivotally attached to the window traine and cooperating means secured to the Window, said means comprising a bracket having a plate extending laterally therefrom, a yoke having its base piveted to said plate and having an upstanding portion through which the rod passes, a collar secured to said upstanding portion and Vfrictionally embracing said rod, and a. resilient split bushing engaging said collar to urge it into trictional contact with the rod.

2. A easement Window adjuster comprising a rod pivotally attached to the window trame, and means to :t'rictionally cooperate with said rod adapted to be attached to the Window comprising a bracket having a plate extending therefrom in a horizontal plane, a yoke pivotally attached to said plate and having a. pair ot' upstanding legs, the legs of the yoke being provided with perforations through which said rod passes, a split collar surrounding said rod and disposed between the legs ol the yoke, and a resilient split metal bushing surroumling the collar and serving to compress it into close trictional engagement with the rod to secure the Window in adjusted position.

3. In a Casement window adjuster, a rod adapted to be pivotally attached to the \viudow frame, a split collar adapted to trietionally engage said rod, resilient means embracing said collar to cause it to tightly engage the rod, and means to prevent longitudinal movenient of the collar relatively to the window.

4;. In a easement window adjuster. a rod adapted to be pivotally attached to the ivindoiv trame, a yoke adapted to be carried b v the Window7 a collar ot tibrous material adapted to embrace the rod and a split bushing engaging said collar to cause it to tightly embraeo the rod, said collar and bushing being mounted in said yoke.

In a asement n'indoiv adjuster. a rod adapted to he pivotally attached to the \vin dow trame, a split collar adapted to l'rirtionally engage said rod. means engaging said Collar to cause it to tightly engage the rod, and means to prevent longitudinal movement ot the collar relative tothe windon'.

In witness whereof, I have hereunto .set my hand this Lith day of January, 19:29.
